Display apparatus

A display apparatus comprising:

• a light source configured to emit a light;
• and
• a display panel configured to display an image using the light provided from the light source, the display panel comprising:
• a first substrate;
• a first electrode disposed on the first substrate
• a first polarizing plate disposed on the first substrate and configured to receive the light provided from the light source and incident to a lower portion of the first polarizing plate and to linearly polarize the light incident thereto;
• a second polarizing plate disposed on the first polarizing plate and configured to circularly polarize the light exiting through the first polarizing plate;
• a third polarizing plate disposed on the second polarizing plate and configured to linearly polarize the light incident thereto;
• a shutter disposed on the first polarizing plate and configured to mechanically deform in a thickness direction of the first polarizing plate in response to an electrical signal, wherein the display apparatus display a grayscale in accordance with mechanical deformation of the shutter;
• and
• a second electrode disposed to face the first electrode such that the shutter is disposed between the first and second electrodes,
• wherein the display panel further comprises an optical compensation layer disposed between the first electrode and the first polarizing plate.

A display apparatus comprising:

• a light source configured to emit a light;
• a first polarizing plate configured to receive the light provided from the light source and incident to a lower portion of the first polarizing plate and having a first transmission axis;
• a second polarizing plate disposed on the first polarizing plate and having a second transmission axis substantially perpendicular to or parallel to the first transmission axis;
• a third polarizing plate disposed between the first and second polarizing plates and having a third transmission axis crossing the first and second axes;
• and
• a shutter disposed between the first and second polarizing plates and configured to mechanically deform in a thickness direction of the first polarizing plate in response to an electrical signal.
